The CDC says eight of 11 people infected and who were interviewed stated they had consumed kratom in some form in the months before they became ill. Illnesses started in October of last year through Jan. 20, 2018. The infected include people ages 6 to 67. Eleven people have been hospitalized and no deaths have been reported.

The CDC says other illnesses might not have been reported due to the two- to four-week period it takes from when a person becomes ill and when the illness is reported.

Currently, states in which at least one infection has been reported include Alabama, Arizona, California, Colorado, Florida, Kansas, Kentucky, Louisiana, Massachusetts, Michigan, North Carolina, North Dakota, New York, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee and Utah.

The CDC is recommending people refrain from consuming kratom in any form as it could be contaminated with salmonella.
